In the equation 3s +135= 4.5 (s +10) what is s
Lubov Fominskaja [6]
3s + 135 = 4.5s + 45

Now move the variables and coefficients

135 = 1.5s + 45

And then the numbers

90 = 1.5s

Simplify

90/1.5 = 1.5s/1.5

60 = s

Hope this helps!

Math question.......................................
ValentinkaMS [17]
Question 1:

The answer is A: Sam.

His table is the only one that follows the conditions set in the question. 

Question 2:

Choosing two points; (0, 14) and (4, 10)

Slope (m) = \frac{10 - 14}{4 - 0} =  \frac{-4}{4} = -1

Thus, equation, 

y -  y_{1} = m(x -  x_{1})  

y - 10 = -1(x - 4)

y = -x + 14

I'm getting that for my equation of the line, so my best guess is that the answer is C.

The reason I got my answer is probably because I made a calculation mistake somewhere. If you use my methods, you should arrive at the correct answer.

The answer is C. ( I believe )

How do I solve this problem
Brums [2.3K]

Answer:

a =9

b= 28

Step-by-step explanation:

The parts of the ratio must be equal

5:7:a = 20:b:36

How do we get from 5 to 20

We multiply by 4

So multiply the first by 4

5*4:7*4:a*4 = 20:b:36

Ratio 1

5*4 =20  true

Ratio 2

7*4 =b

28 = b

Ratio 3

4a = 36

Divide by 4

4a/4 = 36/4

a = 9
